To adjust the position of a newly added field in an Oracle database table, you can follow these steps:

  1. Modify the table structure using the ALTER TABLE statement to add a new field. For example:
ALTER TABLE table_name ADD (new_column_name column_type);
  1. Create a new temporary table and copy the data from the original table into it. This can be achieved by using the INSERT INTO SELECT statement to transfer the data from the original table to the temporary table. For example:
CREATE TABLE temp_table AS SELECT * FROM table_name;
  1. Remove the original table. You can use the DROP TABLE statement to delete the original table. For example:
DROP TABLE table_name;
  1. Recreate the original table, including a new field. You can use the CREATE TABLE statement to create the original table and include the new field. For example:
CREATE TABLE table_name (
  column1 column_type,
  new_column_name column_type,
  column2 column_type,
  ...
);
  1. You can copy data from a temporary table back to the original table by using the INSERT INTO SELECT statement. For example:
INSERT INTO table_name SELECT * FROM temp_table;
  1. Delete the temporary table using the DROP TABLE statement. For example:
DROP TABLE temp_table;

By following these steps, you can successfully adjust the position of newly added fields in an Oracle database table.
